San Antonio firefighters who cannot extinguish a blazing chemical leaking from a derailed train car cordoned off a 2,500-foot area surrounding the site because of the danger of an explosion. Authorities said they do not know how long the car will keep burning. The Sunday derailment had caused five tank cars to ignite, sending thick clouds of black smoke into the air. The car that continued to burn was loaded with toxic butadiene, used in making synthetic rubber.
